Mock server doesn't respond with headers

[alangibson-philips]

Description

When running in mock server mode with an OpenAPI 3 API definition, response headers aren't returned.

Expected behaviour

Headers defined in responses section should be included in response.

Actual behaviour

Only a few standard headers like Content-Type and Content-Length are included.

Steps to reproduce

1. Add any header to an OpenAPI 3 response definition. Something like:

  /Endpoint:
    get:
      responses:
        '200':
          headers:
            cache-control:
              schema:
                type: string
                example: public
          content:
            application/json:
              ...

2. Start connexion with connexion run your_api.yaml --mock=all
3. Request the endpoint with an HTTP client, such as curl -v
4. Observe that the header is not included in the response.

Additional info:

Output of the commands:

• python --version Python 2.7.15rc1

• pip show connexion | grep "^Version\:" Version: 2.2.0

I see you added the enhancement tag to this issue. I'd be happy to look at putting together a pull request if you can point me in right direction. I haven't dug into this codebase before.
